Do some single-celled organisms have special structures to pump excess water?
The structure is called the contractile vacuole. It can pump water out of the cell when there is too much. This way, the excess water won't cause it the cell to burst. They can be found in both animal and plant cells.
How can unicellular organisms without cell walls avoid bursting?
Unicellular organisms without cell walls can avoid bursting by regulating the movement of water across their cell membrane through processes like osmoregulation. They maintain an internal osmotic balance by adjusting the concentration of solutes inside the cell or expelling excess water. Additionally, some unicellular organisms have contractile vacuoles that actively pump out excess water to prevent bursting.
How Do Unicellular Organisms Get Water?
Water just diffuses ( called osmosis ) across their cell membranes down it's concentration gradient. So much so that some single celled organisms need contractile vacuoles to get rid of the excess water so they do not become hypotonic in condition.
What is the function of a contractile vacuole in some in some single-celled organisms?
Vacuoles can store many types of molecules, in particular essential substances that are potentially harmful if present in bulk in the cytoplasm The contractile vacuole stores excess water that enters into it and expels it out after a stage
In some freshwater organisms there is a structure called a contractile vacuole that regulates water movement into and out of the cell. What explains the existence of the CV?
The contractile vacuole (CV) exists in freshwater organisms to manage osmotic pressure. Since these organisms live in a hypotonic environment, water continuously enters their cells by osmosis. The CV collects excess water and periodically expels it, helping to maintain osmotic balance and prevent cell lysis. This adaptation is crucial for survival in freshwater habitats where the external water concentration is higher than that inside the cell.
What are some methods organisms have develop for removing excess water?
humans sweat to remove water

Which organelle helps keep some unicellular organisms from bursting as they absorb water by osmosis?
Contractile vacuole helps regulate water intake and prevent bursting in unicellular organisms by pumping out excess water that enters the cell by osmosis.

What is necessary for soil conservation?
How you plant, what you plant, how you water, and how you harvest all affect the soil. Some methods result in excess erosion, while others conserve soil.
Organelles that collect excess water inside the cell and force water out are called?
The organelles that collect excess water inside the cell and force it out are called contractile vacuoles. It is primarily involved in osmoregulation and is usually found in protists and unicellular algae.
How do organisms get rid of water?
Organisms eliminate excess water primarily through processes such as excretion and transpiration. In animals, this occurs mainly through urine produced by the kidneys and sweat from the skin. In plants, water is lost via transpiration through tiny openings called stomata. Additionally, some organisms can release water vapor during respiration or other metabolic processes.
What are some methods organisms use to regulate internal temperature?
sweating

Contractile vacuoles are found in the eukaryotic cells of some?
organisms, particularly protists, to regulate osmotic pressure by expelling excess water. The contractile vacuole acts like a pump, collecting water and then expelling it from the cell to prevent it from bursting due to osmotic imbalance.
